Fuel filter problem

[Sfrid073]

Ok, I'm back again. Went to change the fuel filter on my 1997 Blazer LT AWD. Guess I should have doen it sooner. Trucks got 102000 miles and its still the original filter. Well the nut is frozen. I used flare wrench so as not to round the nut over, soaked it in BP Blaster. Still wont budge. Obviously no heat can be used here. Any other ideas?

keep on soaking it and use two wrenches to loosen the connector.

One on the filter nut and one on the connector.

Also, maybe try a different penetrating oil like wd40 or something.

Hey just a quick question:
I just bought a set of metric flair wrenches and they are all to small to fit the fuel filter. What size wrench are you using?

[BlazerLT]

I used two small adjustable wrenches.

Use a 5/8" and 11/16" tubing wrench. Kroil is a good penetrent. Make sure you spray the tube into the nut also, that is more than likely where the problem lies.
